It's a logo representing a clown fish with the fish facing to the right. The fish has for fins and a tail fin. There is one eye visible and two sets of curved parallel lines like a clown fish would usually have.
This is a Clown Fish icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,300 icons, all in the same style and quality.
